Specification of Letters Patent.

Patented Mar. 13, 1917.

Application filed March 16, 1915. Serial No. 14,790.

To all whom it may concern:

:6 it known that I, Josnrn I'IALSIG, a subject of the King of Prussia, residing at S (loetersstrasse, in the town of Viersen, Rhine Province, Germany, have invented new and useful. Improvements in Machines for Bagging and Veighing Granular and Powdery Substances, Particularly Cocoa Powder, of which the following is a specification.

Automatically working machines exist in which the substances to be weighed are first filled into packages, for instance, bags, boxes, or the like, in approximate quantities ainl are thereafter brought to weight by accurate weighing. The present invention relates to a particular constructive form of such a machine.

In the machine according to this invention the packages are also passed, by means of a revolving supporter, singly below an adjustable measuring device which fills the package with the larger portion of the charge to be weighed whereafter the continued movement of the supporter places the charged packages upon a weighing device to receive, while the movement of sup-- port is stopped, a further filling charge to bring the previously measured packing up to the desired weight.

According to this invention the movement of the revolving support controlled by means of a mercury contact, a. magnet, and a double coupling.

In the. accompanying drawings,

Figure 1 shows a front elevation and Fig. 2 a side elevation of the machine.

Fig. 3 is a part-sectional view of the machine, while Fig. 1 shows a section through the bagging device.

Fig. shows a top view and Fig. 6 a ear view of the transmission 'ear. b Fig. 7 is a top view of the weighing device.

Fig. 8 shows two enlarged views of the cam disk 48.

Fig. 9 shows enlarged views of the weighing device.

In Figs. 10 and 11 a device for placing the bags or the like packages upon the weighing pan for supplementary weighing is shown in top views.

Figs. 12 and 13 are details of the mercury contact showing the parts in different positions.

The substance to be weighed is fed into the funnel 1 by hand or by mechanical means. The funnel 1 is fixedly mounted upon the bridge 2, and is provided with a stirring arm 3 and a conveying worm 4-; Fig. 1.

iiQlUvV the bridge 2 a revolving support or carrier is moving that consists of a shaft 5 mounted in a hub 6 of the bridge 2 and a bearing disk 7 and upon which the revolving disks 8 and 9 are fastened. These disks are each provided with four or more bore holes or openings placed at equal distances apart in a circle. The upper revolving disk 8 is constructed as a sprocket wheel and carries tubes 10 fixed below the openings. These tubes are a continuance of the openings in the disk. The revolver is mounted in such a way that the openings of the revolving disks 8 and 9 can. be singly brought to register with an opening provided in tl e bridge for the bagging device.

The paper bags or containers to be filled are slipped over the tubes or nozzles 10 in such a wav that the bottoms of the bags stand freely within the o 'ienings of the disk D.

The bridge is mounted upon two columns 11, 12, fastened on the table 13.

The machine may be operated from a pullev 1.5 by means of a small electromotor which is to be placed upon the base plate 1%. The pulley 15 rotates the shaft 18 through the gear wheels 16, 17.

One bearing of the shaft 18 is mounted upon the post 19 while the other bearing is screwed onto the machine box 20.

Upon the shaft 18 is loosely rotated. the belt pulley 21 which. on one face is provided with a toothed coupling disk. In addition, the shaft 18 carries, on the other side, the toothed gear wheel 22 which is also provided with a toothed coupling disk. Between the belt pulley 21 and the gear wheel 22 the shaft 18 is made of greater diameter, and upon this strengthened part the double faced coupling 24: (Figs. 7, 8) is slidably mounted on a key 23 partly sunk into the shaft. A clutch lever pivoted in the post 26 engages the coupling. )ne end of the clutch lever 25 projects into the machine has 20 and is pivotally connected to the boss which is screwed to the ironcore of the electro-magnet 28 Figs. '2, The electro-magnet is mounted upon two columns 29, 30, and is connected througl an electric conductor with the conductor of the driving motor, both parts being operated through one switch.

The weighing device is mounted within the machine box 520 and consists of a balance beam ill carried on a knife edge by the housing 1:32. ance beam At both ends of the the scales 33, But, are suspended on knife edges. (Figs. l For supporting the charge. the weighing scale I'llcai'ries above the weighing cam 31 a pan 35 which pro liccts through an opening of the table 13.

The weighing scale 33 serves for *arrying the stamped weights which the weight of the packages is to be made to equal.

Ono carrying rod ol the scale ill provided with an arm 37 which carries. on a readily movable lever a8, a mercury contact 39, consisting of an exhausted glass tube having two contact pieces soldered in and containing a small quantity of mercury.

The mercury contact 39 swings easily in the bearing t0 and the contact pieces are connected to the insulated screws all, d2, by means of readily movable coiled wires. T he conducting wires of the magnet 28 are also connected to these screws.

The operation is as follows:

To set the machine into operation the motor is switched on and the conductors oi the magnet are simultaneously subjected to the current. It is supposed that the machine is in the position when a weighing action is being finished.

Atthe moment oi finishing a weighing action the s-ale get with the weighing pan 35 is lowered so much that through the arm 3? the mercury contact 39 has been inclined l ar enough to cause the mercury to leave both contact pieces thereby brca king the contact. The flow of the current to the magnet ceases and the iron core together with the lever 25 (Fig. 3) goes down.

its this moment the double coupling 2i engages the toothed disk oi. the gear wheel 22 and rotates same. Gear wheel drives at this time the g ar wheel t?) fixedly mounted upon the shaft ll. Through the toothed gear 4:5 the vertical. shaft 46 is driven and rotate. the sprocket wheel of the revolving disk 8 through the sprocket wheel 1+? and an endless chain and thereby the supporter is rotated (Figs. 1, 2). Through the movenent of iii; revolving supporter the finished weighed bag is moved from the scale pan on to the table 13. The revolving disk 9 keeps the weighing pan 35 and consequently the whole 'ghing device in its lowest position until the revolver is turned far enough to bring the next opening of the revolving disk 9 into osition above the weighing pan which hereupon moves up into the opening.

During the tine the revolver moves through a quarter turn to bring the next opening oil? the revolving disk over the weighing device. tl oi-responding upper opening with the 1 attached passes the bagging device.

is soon as a portion of an opening of the revolving disk 8 covers the opening of the bagging device in. the bridge the cam drum l8, fixedly mounted upon the shaft l, moves by means at the lever l!) that is nvoted in the post 50, and by means of the conncc 11'. g rod 51 and the clutch lever 52 the slidable coupling into engagement with the toothed disk of tl e sprocket wheel 54: and rotates same. Thereby, the endless chain oi" the sprocket wheels 55, 56, as well as the sprocket wheel 57 fixedly mounted upon the shaft 58. is rotated (Fig. 2). By means oi the toothed gear ("1- MA I" +121 tllC stirring arm 3 and the worm l within the tunnel 1 are rotated and the substance contained in the tunnel is fed into the bag in the desired quantity (Fig. t).

Before the opening of the revolver leaves the tunnel opening entirely, while the volriug supporter continues to move, the cam drum 4t-8 disengages the coupling The cam drum 48 consists of two iarts, each having a cam 7) (Fig. 8). By varying the relative position of these parts by means of slots and screws o the cams Z2 may be adjusted for shorter or longer coupling periods so that a correspondingly larger or sma ler quantity of substance will be fed into the bag while the support is revolving. Since the charges usually vary in weight for an amount u to grams the adjustment is to be chosen so that betw .en and 10 grams are wanting in the proper weight ot the bag which minus is thereupon supplied by the supplementary weighing device.

'llhrough the continued movement of the revolving supporter the charged bag arrives at the weighing pan which is released by the opening in the disk 9 to rise. T he small difference of weight between the charged bags and the weight the bag to have finally permits but a slow rising of the scale and the weighing pan To obtain a quick and sudden rise 01 the weighing scale an auxiliary weight lever 60 is pivotally mounted on a stud "51 below the weigl'iing beam 81 (Figs. 1, This lever carries at its opposite end the weight The weighted lever 60 presses the weighing beam 31 and the weighing pan (it) quickly into the opening 01. the revolving disk 9. At the same time the arm 37 hits the mercury contact 39 and switches the magnet 28 on. The double faced coupling 24 disengages the toothed coupling disk of the gear wheel 22 and thereby stops the shaft 44: and consequently the revolving supporter. The double faced coupling 24 immediately rotates the belt pulley 21 by engaging its coupling disk, and sets the supplementary weighing device into operation.

At the same time a bell-crank lever 63 is magnetically attracted which is pivotally fastened within an opening of the tappet 7 of the iron core of the magnet 28. Through the connecting rod 64 a rail 65 is moved and raised at one end. Thereby, the roll or ball 66 lying upon the rail 65 rolls toward the end 67 of the rail 65 which moves on the guide rolls 0 and (Z. A stop 68 provided on the rail 65 rocks the lever 69 and the latter raises the weight 62 of the lever 60 and thereby releases the weighing beam (Fig. 1).

For supplying the additional quantity of substance :1 conveyer worm 71 is mounted in a box on a shaft 72 which is driven by means of a belt pulley 73 from the belt pulley 21 on the shaft 18 (Figs. 2, 7, 9).

Above the worm 71 a shaft 74 is mounted in the walls of the box 70, which shaft carries the stirring frame 7 5. This stirring frame 7 5 is operated by means of a lever 7 6, a spring f and a cam disk 77 fastened upon the shaft 72. Through these connections the stirring frame 7 5 is given a rocking movement within the box 70 to prevent the substance therein from clogging or bridging.

The Worm 71 feeds the substance through an adjustable opening 78 in form of a fine stream into the charged bag upon the weighing pan 35. The additional filling effects a slow sinking of the weighing pan 35, and at the moment the precise weight is obtained the already inclined mercury contact 39 switches off the magnet 28. The double coupling again engages the toothed coupling disk of the gear wheel 22 and the finished bag is removed while another bag is placed upon the supplementary weighing device.

hen the iron core of the magnet is re leased the bellcrank 63 and the rail 65 are restored to their former position; the lever 69 is left behind and is pushed back by the roll 66 which runs down from the end of the rail 65 to its former position, thereby releasing the auxiliary weight lever 60 which now presses again the pan with the next bag quickly up.

Through the running action of the roll 66 upon the rail 65 a space of time is gained that is required to turn the revolving supporter far enough to prevent the weight lever 60 from pushing up again the weighing pan 85 with the finished bag still thereon.

The auxiliary weight lever 60 is released by the running action of roll 66, when the charging funnel, a coacting rotatable carrevolving supporter is turned so far. that pan 35 is locked in its depressed position by a solid portion of the revolving disk 9. To insure that the bag to be weighed may be placed upon the weighing pan without rubbing against the revolving disk 9 a plac ing device is arranged upon the table 13. This device consists of a lever 79 and the cam lever 80 both of them being adjustable relatively to each other and rotate together on a stud 81, a spring 82 keeping the device in. working position. On the revolving disk 9 bosses 83 are provided. While the revolving supporter is moving the be. es swing the cam lever 80 of the placing do. e and the bag is thereby placed in advance of the movement of the revolving disk upon the weighing pan The placing device thereafter jumps back owing to the action of the spring 82 against the stop 84, and the bag is left standing upon the weighing pan 35 with a clear space around it.
